Abstract: A cookware article comprises a body formed from an aluminium alloy plate defining an interior cooking surface and an exterior surface. The exterior surface bears a hard-anodised layer having a porous oxide matrix within which copper ions are electrolytically infused and mechanically retained, imparting a durable, integral copper- toned finish. The interior cooking surface, free of any hard-anodised layer, comprises raised lands and recesses formed directly in the aluminium alloy in a repeating pattern, configured to promote lateral heat conduction and define air pockets for enhanced food release. The interior cooking surface further bears a blasted finish formed after patterning, imparting controlled surface roughness and work-hardening the aluminium. A non-stick coating applied over the interior surface is mechanically protected by the raised lands. A corresponding method of manufacture is also disclosed, comprising cutting, forming, anodising, ion infusion, patterning, blasting, coating, cleaning, and packaging steps. Ref: Fig. 1
